Claims.

This invention relates to punching or perforating machines and more particularly to machines of the type in which punching maybe controlled either manually or by a previously punched card.

The principal object is to increase the general flexibility of a card reproducing or duplicating machine so thatreproduction of certain data on a punched card may be effected in accordance with certain other data on the punched card. Where it has heretofore been desired to reproduce data in particular fields of a punched card and tosuppress data punched in other fields, so-called skip bars and column cut-out bars have been provided to efiect a machine set-up whereby the same fields of each punched card to be reproduced would be rendered active and the same fields in each suppressed.

In certain classes of work, this machine set-up is not sufliciently flexible where it is desired to suppress or reproduce data in a particular field of the punched card accordingly as the card is punched in a specially designated field or not. Further mechanism is incorporated in the machine and may be operated in conjunction with the regular column skipping and cut-out devices effective in certain fields of the punched card whereby upon the occurrence of a specially located perforation in such fields, the reading and reproduction of data in the field containing such special perforation will be suppressed and the field automatically skipped. If the special hole is absent, all or part of the field may be effective to punch reproduction data in the new card.

Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings; and the invention also constitutes certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the drawings:

Fig. '7 is a detail of the essential operating elements of the punching section of the machine.

Fig. 8 is a detail of the punch controlling contact and the operating device therefor.

The punching machine is generally of the form shown in the Lee and Phillips Patent No. 1,772;- 186, granted August 5, 1930 and the description thereof will be limited to the features essential to an understanding of the present invention.

In Fig. 7, punch selecting magnets 10 are provided, there being one for each index point position of the record card. Energization of magnet 10 will attract its armature to rock an arm 11 in a counterclockwise direction about its pivot 12. thus moving key 13 downwardly to rock a bell crank 14 which has connection with an interposer 15 which is suitably mounted for horizontal reciprocation. The forward end of interposer 15 is suitably guided between an operating bar 16 and the upper end of a punch 1'7.

Forward movement of the interposer will position its widest portion between bar 16 and punch 17 so that subsequent counterclockwise rocking of bar 16 about pivot 18 will move the interposer and punch downwardly to perforate the record card 19. A notch 20 in the interposer-cooperates with a bail 21 to rock the same in a counterclockwise direction when the interposer is moved toward the left. Rocking of ball 21 in such manner will draw a hook-shaped'member 22 (see Fig. 8) toward the left to close a pair of contacts 23.

As will be explained in connection with the circuit diagram, contacts 23 complete a circuit through the punch magnet 24 causing it to attract its armature 25 and through linkage generally designated 26, draw downwardly on the bar 16 to cause depression of the selected punch. De

pression of key 13 may, of course, be effected independently of the operation of the magnet 10 for the purpose of manually controlling punching operations.

Disposed beneath the interposers 20 is a ball 27 which is carried by rod 28 upon one end of which is secured an arm 29 (see Fig. 5) for operating the e'scapement mechanism. The escapement mechanism comprises a holding pawl 30 pivoted at 31 to the frame of the machine and a stepping pawl 32 loosely pivoted on rod 28 and normally urged by a spring 33 into engagement with the teeth 34 on the upper edge of'the carriage rack 35. Rocking of rod 28 in a counterclockwise direction under action of an interposer 15 will lower pawl 30 into engagement with a tooth 34 to hold the rack in position while punching is being effected. This action at the same time raises pawl 32 out of engagement with teeth 34 and by virtue of its loose connection with rod 28 will move slightly toward the right in readiness to intercept the next tooth 34 when the rod 28 is returned to its original position.

Referring to Fig. 1, the rack 35 is suitably mounted for horizontal movement in the frame of the machine and maybe manually moved toward the right to the position shown wherein a record card 19 is placed in position with the first column thereof in line with the punches 17. Gear teeth out on the underside of the rack cooperate with suitable gearing 41 which is connected to the usual spring barrel 42 which tends to move the rack toward the left and which effects such movement under controlof the escapement mechanism just described. V

Rack 35 is provided with extensions or arms 43 and 44 between which a pattern or master card 45 is positioned and which is adapted to be moved back and forth with the rack. An arm 46 carried by the rack 35 is provided for cooperation with the card 19 to move it column by column past the punches 17. Positioned above the pattern card 45 is a contact roller 47 (see also Fig. 2), which is insulated from the frame of the machine and supported by a door 36 pivoted at 37. A pair of contacts 38 is adapted to be closed when roller 47 is in its down position as in Fig. 2. Directly below the roller 47 is a row of brushes 48 carried by a bar 49 which is normally in the position shown in Fig. 2 holding the brushes down out of engagement with the card 45. A magnet 50, upon energization, will attract its armature 51, actuating linkage 52 to cause upward movement ofbrushes 48 into engagement with the record card. This brush operating structure is fully shown and described in the copending application of Lee and Daly, Serial No. 391,874, filed September 11, 1929, to which reference may be had for further details of construction. A contact 53 is closed when armature 51 is attracted to elevate brushes 48 into contact with roller 47.

Referring now to Figs. 5 and 6, shaft 55 which carries the bail 21, is rocked from the position shown in Fig. 7 to that of Fig. 5 by the shifting of an, interposer 15 and a T-shaped element 56 secured to shaft 55 is rocked slightly counterclockwise. A spring 57 is coiled about shaft 55 and has its ends abutting element 56 and an element 58 loose on shaft 55. Element 58 normally abuts a lug 59 of a member 60 loose on shaft 28, the result being that spring 57 is coiled about shaft 55 as the element 56 is rocked. When the stepping pawl 32 is subsequently rocked, the upper edge thereof, contacting with an arcuate lug 61 of member 60, will elevate the latter, permitting the element 58 to follow element 56 under the influence of spring 57. Member 60 carries a pin 62 in its free end which, when member 60 is rocked, serves to open a pair of contacts 63 and close a pair 64. The function of these contacts will be explained in connection with the circuit diagram.

As bail 21 is returned to its normal position, member'56 will engage element '58 to rock the latter clockwise during the return movement of bail 21. By virtue of this construction contacts 63 and 64 remain in their shifted position until the advanced interposer is fully restored.

In Fig. 8' is shown an arm 55a secured to shaft 55 which is adapted to be engaged by an extension of link 26 to cause rocking of shaft 55 whenever the punch bail 16 is operated. This results in the actuation of contacts 63. 64 as though an interposer 15 had rocked the shaft.

Fig. 3 shows the mechanism for cuttin out reproduction punching in certain predetermined columns or fields to permit manual punching of the columns or fields cut out. This may comprise a bar 65 fixed to the base of the machine and which has cut-out portions 66 coextensive with the columns or field to be duplicated and cam portions 6'7 adapted to engage a lug 68 of lever 69 pivoted at 70 tocarriage arm 43. Lug 68 presses against a bail 71 and rocks a rod 72 on which the bail is mounted. Projecting downwardly from the rod 72 is a finger 73 which upon turning of rod 72 as described opens a pair of contacts 74.

The mechanisms briefly described above are now well known in the art and further explanation thereof may be found in the patents referred to and in the application of Fred Lee and George F. Daly, Serial No. 391,874, filed September 11,

For the purposes of the present invention a brush carrier 75 is mounted upon arm'44 and provided with pairs of brushes 76 and 77. Brushes 76 are electrically connected and bridge a pair of contact segments 78 when the thirtyfourth column of the card 19 is under the line of punches 17 and bridge a second pair of contact segments 79 when the fifty-seventh column of the card is under the punches. Brushes 77 successively connect segments 80 and 81 with a common conducting segment 82. The several segments are imbedded in a support 83 of insulating material which is rigidly secured to the base of the machine.

The complete operation of the machine will now be traced with particular reference to Figs. 1 and 4. The latter figure shows a card of the "dual service type used in connection with public utility statistics and accounting. The left hand portion of the card may contain data representative of the account number, meter reading dates, route location, date of payment, etc. The remainder of the card is divided into two similarly outlined fields labelled G and E, the former adapted to receive data concerning "gas and the latter, similar data concerning "electricity. The card of a customer to whom both types of service are furnished will have data punched in both the G and E fields. The card of a customer to whom only one type of service is furnished will have only the field corresponding to that type of service perforated and a perforation 85 will be made in the first column of the unused field in the "11 index point position.

Assume that a punched card 45 has been placed in the appropriate card carriage and a blank card 19 in its carriage and that column cut-out bar 65 is cut so as to maintain contacts 74 open during the punching of certain of the first thirtythree columns of the card. In the columns to be key punched, contacts 74 will be open, and they will be closed in columns that are to be duplicated under control of the corresponding column of card 45. The punching in the first thirtythree columns is in accordance with the usual practice and a representative circuit will therefore be sufiicient to explain the operation. Depression of any key 13 will close contacts 23 (Fig. 1) completing a circuit from source S, wire 94, contacts 23, punch magnet 24, wire 86, back to source This causes the perforation of the index point position corresponding to the key depressed and the automatic escapement of the cards to the next column.

In columns to be duplicated the following punch selecting circuit may be traced. From source S, wire 86, contacts 63, wire 87, roller 4'7, hole in card 45, brush 48, cable 88, corresponding magnet 10, wire 89, points 90a. of relay 90, wire 91, relay 92, column cut-out contacts '74 (now closed), wire 93 to source S. Energization of magnet 10, causes selection of a punch and closure of contacts 23 which in turn complete the above traced circuit to the punch magnet 24 to effect punching and escaping.

When the thirty-fourth column of card arrives at the brushes, contacts 74 are closed and brushes 76 bridge segments '78. If there is an X perforation in column 34 of card 45, the entire field G is to be skipped and this is effected as follows: A circuit is completed from source S, wire 86, contacts 63, wire 8'7, roller 47, X perforation in column 34, brush 48, cable 88, wire 95, segments 78 (bridged by brushes '76), wire 96, relays 97, 90, wire 98, wire 93, to source S. Energization of relay 90 which is of the quick acting type, opens its points 90a. to prevent the perforating of the X position of column 34 of card 19. Relay 9'7 closes its points 97a; to set up a holding circuit which extends from source S, wire 99, common strip 82, brushes 7'7, strip 80, wire 100, points 97a, relays 97, 90, wire 98, wire 93 to source S. This circuit will hold throughout the analysis of the G field of card 45.

The G field is skipped by successive operations of punch magnet 24 which is operated without accompanying punching. The skipping is effected upon closure of points 901) which cause completion of a circuit from source S, wire 93, wire 101, points 90?), wire 102, points 92a, wire 103, contacts 53 (now closed), magnet 24, wire 86 to source S. Energization of magnet 24 will cause the card to skip to the next column and as explained above the action of the punch mechanism, causes rocking of bail 21 to close contacts 23 and 64 and open contacts 63. Contacts 23 take the punch magnet circuit from the control of the more delicate relay points 90b and 92a.

Contacts 64 energize relay magnet 92 causing points 92a to open and the timing of the various operations is such that contacts 23 open to break the punch magnet circuit while points 92a are open.

Upon reopening of contacts 64 at the end of the escapement action, relay magnet 92 is deenergized and closure of its points 92a will repeat the circuit through the punch magnet which will again close contacts 23 and contacts 64. In this manner the relay points 920. are caused to repeatedly energize the punch magnet 24 and such action will continue until the holding circuit of relay 90 is broken at brushes 7'7, at which time column 57 which is the first column of field E is at the punching station and operations from this point will continue in the same manner as the operations effected in punching the left hand portion of the card. That is, all or part of the E field may be duplicated, part may be key punched and certain sections may be skipped.

The automatic skipping of the E field is effected in the same manner as described for the G field except that the holding circuit is maintained through strip 81 and an X hole in the fifty seventh column effects the initial energization of relays 97 and 90.

It will be noted that when either of the fields G or E is being skipped, relay points awhich lie in the common return line 89 of the selector magnets 10, are open thus preventing the selection of punch interposers if there should be perforations in the skipped field. It is also apparent that if columns 34 and 57 are both X punched, both fields will be automatically skipped.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
